Homohgenization with general microtensor fields
by Alexandros STATHAS Nov. 22, 2024

Nov. 22, 2024

Dear all, I am a new user of sfepy that was attracted to this FE code because of the homogenization engine. I am trying to solve a microproblem using the homogenization engine of sfepy. In my case the microsopic variable is not a vector -like $u^1_i$- but a tensor $\omega^1_{ij}$. As I understand sfepy provides the CorrDimDim class for storing the resulting microfield for the differnt unitary loads (pis). This class works fine if the unknown is a vector, but in my case it is a second order tensor how can I implement a Corr2Dim2Dim class or even more general CorrNDimMDim class for storing the values of more general fields? Thank you in advance for your help,
